ADXL356BEZ使用故障

pennykx — Mon, 06 Jul 2026 07:18:43 GMT

ADXL356BEZ 加速度计，装在产品上出现的故障现象，放在平板上动一下倾角再放平，显示的值回不到原来的零位值了，把这个焊下来换一个新的就正常了，目前装了150片，发现了6片这样的，见视频，请问这可能是什么原因造成的呢？ez.analog.com/.../348a0d7e95762b3b754b3b21d20ccd79.mp4

这个描述的意思是 X轴数据高位只用了4bit，低位也只用了4bit的意思吗？但是为啥说是12位？

adxl367 产生中断后，主mcu读取完毕传感器数据，adxl367的status 寄存器的DATA_READY bit不置0

GuangGuangde — Fri, 15 May 2026 09:18:36 GMT

主mcu通过i2c接口与adxl367通信，通信数据为400k
上电后处理流程如下：
1、配置复位寄存器
reg_soft_reset=0x1F，value=0x52
2、读取芯片信息
reg_devid_ad=0x00,value=0xAD
reg_devid_mst=0x01,value=0x1D
reg_parid=0x02,value=0xF7
reg_revid=0x03,vale=0x03
3、配置功能寄存器
reg_filter_ctl=0x2C,value=0x00 （Range:±2g，ODR：12.5Hz）
reg_intmap2=0x2B,value=0x01 （enable DATA_RDY）
reg_power_ctl=0x2D,value=0x02 （Start mesurement）
4、INT2中断服务例程中读取status寄存器值，DATA_READY位有效时一次行读取0x0E~0x13中的6个数据，读取数据后再次读取status寄存器值为0x41,DATA_READY bit不置0；INT2中断也只产生一次
5、在1s定时器中读取status寄存器值，DATA_READY有效时,一次性读取0x0E~0x13中的6个数据，读取数据后再次读取status寄存器值为0x41,DATA_READY bit不置0

ADXL345的内部滤波器的衰减曲线是什么样的

fate42 — Fri, 24 Apr 2026 01:52:05 GMT

当设置ODR=3200HZ，用做检测±1g的振动G值，从振动频率只有400HZ时测量值就开始衰减是符合滤波的衰减曲线的吗

ADXL357，Y轴出现异常；

AlanYu — Wed, 22 Apr 2026 07:41:40 GMT

ADXL357测量Z、Y两个方向的振动加速度，STM32通过SPI读取后，再通过DAC输出两个通道值：0g时输出5V，+0.5g输出10V，-0.5g输出0V；

①0g加速度时，通道Z输出正常，DAC保持输出5V±0.001V。通道Y输出异常，DAC电压从5V±0.001V缓慢下降至4.95V后，再恢复到5V，见下图；

②上图中加了高通，纵轴换算成了加速度g，也就是缓慢负向变动了约50mg；

③出现上述异常的概率较低，不容易复现。硬件上，两个通道的处理方式一模一样；

④STM32主控：STM32H723VGH6。DAC芯片：DAC8760IPWP；

Could you please tell me if there is a driver for the AD7768 in the Zephyr system?

JimHuang — Sun, 15 Mar 2026 11:18:49 GMT

Is there a driver for the AD7768 for the Zephyr system? Or is there a plan to develop a driver for the AD7768 on the Zephyr platform?
Zephyr is a relatively new operating system for embedded systems, somewhat similar to Linux. Currently, the AD7768 project is used in two products: one is on the single-chip microcontroller STM32H753, which is a Zephyr system; the other product is on the RK3588, where the AD7768 is connected through an FPGA.

The adxl367 uses fifo, non-interruptible mode

jike — Wed, 10 Sep 2025 08:19:37 GMT

My intended purpose is to read the latest 64*2 sets of three-axis data from the FIFO, as configured in my setup: I have configured the FIFO in stream mode, set the FIFO_SAMPLES register to 64, and set the ODR to 400Hz. Of course, I'm not using interrupts but polling once per second to read data.

I believed that when reading from the FIFO via I2C, there should be 64*2 sets of three-axis data, with older data being discarded; however, in practice, I observe that the FIFO is always full (513 data points) when I read it, which is confusing to me. Could you help explain this?

My requirement is to poll the FIFO once per second to read data, and I expect the FIFO to keep only the latest 64 sets of data in the FIFO.

Here is my detailed code.

The adxl367 uses fifo, non-interruptible mode, and is unable to obtain a specified number of data

jike — Tue, 09 Sep 2025 02:09:39 GMT

I use the FIFO of ADXL367 and set it to stream mode, hoping to save 64 sets of X, Y, and Z-axis data with a sampling frequency of 400Hz. I poll the FIFO data every 1 second (without using interrupts), but I always find 513 data entries when reading the FIFO, which is inconsistent with the manual description. How should I configure it to achieve my desired functionality?

this is my code

uint16_t adx1367_get_fifo_xyz(uint16_t *buff)
{
uint8_t data_buff[512 * 2] = {0};
uint16_t fifo_entries = 0;

adxl367_get_register_value(reg_val, ADXL367_REG_FIFO_ENTRIES_L, 2);
fifo_entries = ((reg_val[1] & 0x03) << 8) | reg_val[0];
if((0 == fifo_entries)){

for(int index = 0; index < fifo_entries; index++){
buff[index] = (data_buff[index * 2] << 6) + (data_buff[index*2 + 1] >> 2);
}
return fifo_entries;
}

return 0;
}

void adxl367_fifo_setup(void)
{
sample_mode_info_t *p_sample = NULL;
uint8_t reg_value = 0;

p_sample = sample_config_get();

// Set fifo stream mode
adxl367_get_register_value(&reg_value, ADXL367_REG_FIFO_CONTROL, 1);
reg_value &= ~(3);
reg_value |= ADXL367_STREAM_MODE;

// Set fifo sample x,y,z
reg_value &= ~(0x0F << 3);

// set fifo sample 64/1
reg_value &= ~(1 << 2);
adxl367_set_register_value(reg_value, ADXL367_REG_FIFO_CONTROL);

// set fifo sample 64/1
reg_value = 0;

ADXL367设置FIFO采样长度后，使用轮询方式1s读取一次(非中断)，但和预期的不一致

jike — Mon, 08 Sep 2025 09:32:55 GMT

我使用ADXL367的FIFO，并设置为流模式；采样频率为400Hz，FIFO长度设置为64；我每隔1s轮询读取FIFO中的数据(不使用中断) ，但是我发现FIFO中总是513、512条数据，不是我预期的64个数据；有什么方式可以实现我的功能吗？

this is my code

uint16_t adx1367_get_fifo_xyz(uint16_t *buff)
{
uint8_t data_buff[512 * 2] = {0};
uint16_t fifo_entries = 0;
uint8_t reg_val[2] = {0};

void adxl367_fifo_setup(void)

sample_mode_info_t *p_sample = NULL;
uint8_t reg_value = 0;

p_sample = sample_config_get();

adxl355读数异常，三轴中某一轴数据始终为0

noway1 — Tue, 29 Jul 2025 08:21:14 GMT

adxl355芯片，我这边做了一批设备，一开始全部工作正常，后续有一次经拆装后，个别出现了三轴中某一轴读数全为0的情况，其余两轴读数正常（还有一个是xz轴异常，y轴正常，其余的为X轴异常，yz正常或z轴异常，xy正常），请问出现这种现象可能的原因是什么？拆装过程中过大的外部激励是否会导致这种现象，以及有什么解决方法？

When using the EVAL-ADPD4100-ARDZ evaluation board, none of the register configurations for Timeslot A can be written successfully.

InSideYy — Thu, 24 Jul 2025 08:12:06 GMT

I am using an nRF series CPU to communicate with the EVAL-ADPD4100-ARDZ development board via SPI. IOVDD is set to 3.3V, and AVDD, DVDD1, and DVDD2 are set to 1.8V.

The following register configurations have been written to the ADPD4100.

0009 0080 # 32MHz trim - trim your own clock
000B 02B2 # 1MHz trim - trim your own clock
000C 0012 # 32kHz trim - trim your own clock
000D 2710 # 100 Hz
000F 0006 # enable 1MHz osc
0010 0000 # one timeslot
0020 0004 # in1 connected to vc1 during sleep, everything else floating
0021 0000 # all inputs single ended, vc1 set to Vdd during sleep
0022 0003 # gpio0 is output, inverted
0023 0002 # intx to gpio0
0014 8000 # fifo thresh interrupt to intx

## timeslot A - continuous connect mode - green PPG

0100 0000 # Rin = 500, tsA offset = 0, skip subsample
0101 40DA # path = TIA + BPF + INT + ADC
0102 0001 # IN1 to channel 1, others disconnected
0103 5002 # precondition inputs to TIA_Vref, VC1 active state = V_delta
0104 03C0 # Rf = 200k Rint = 400k
0105 0707 # 11 mA on LED1A, 2A, 3A
0106 0007
0107 0140 # 64 pulses
0108 0000 # period set by automatic period of continuous connect mode
0109 0210 # led width= 2us led offset=16 us
010A 0003 # integrator width=3 us
010B 0210 # integrator offset=16.5 us - ADJUST FINE OFFSET
010C 0001 # no modulation
0110 0003 # signal size = 3 bytes
010D 0099 # -++- int pattern
010E 0000 # NO OFFSET - review if needed
010F 0000 # NO OFFSET - review if needed
0112 0000 # no decimation

The chip is able to correctly read back the Chip ID and the following register configurations

However, all registers in Timeslot A read back as 0x0000 and cannot be written correctly.

I performed additional tests: after enabling both timeslots A and B and writing configurations to their respective registers, I found that the registers for Timeslot B can be written and read back correctly.

ADXRS645的高温陀螺仪传感器芯片是否正常使用的检测问题，该如何确定这个芯片是否是好的？

Valor — Tue, 08 Jul 2025 02:39:40 GMT

问题1：在常温静止下，开始给陀螺仪芯片供电，芯片的输出引脚刚开始是在1.78~2.05v之间跳动，20s时间后芯片输出变成了0.35v左右变动，并且每次重新通电都这样；在自检ST1通电后，芯片输出引脚电压数值不变，请问这个芯片是否坏了？

问题2：如果拿到一个芯片怎么确定这个芯片是好的，可以正常工作的？

ADXRS642的温度输出值只有0.66V

NANTONG — Fri, 18 Apr 2025 08:27:18 GMT

电路图参考了Evaluation Board User Guide UG-262, 5V供电的，发现在室温下温度引脚输出只有0.66V，我用热吹风催了一下，输出会变化。看ADXRS642的温度曲线，室温下应该在2.4V样子，差很多，请问这是哪儿出了问题？

adxl382的iic读取数据正常，但是spi似乎完全没有响应

adxl382的iic读取数据正常，但是spi似乎完全没有响应，连id都读不到，逻辑分析仪上看协议也正确，请问如何调试呢？

CN0507的GUI软件无法搜到串口

Tanker — Tue, 08 Apr 2025 09:15:49 GMT

使用ADICUP3029连接CN0507，其中ADICUP3029使用USB线缆连接到PC端（win11系统），CN0507评估板使用6V供电，电流1.1A。可以发现COM1串口，也能识别U盘，按操作步骤逐条设置，无法在GUI中搜到COM口，请问该如何配置或判断是3029故障？尝试切换3029的拨动开关也没有成功。

也尝试用串口助手发送0x0501没有反馈。固件使用的是从软件GUI里自带的：cn0507-vna-app-firmware-20033101.hex。

请问我该如何检查，还是返修？
