I use pin 3 of port 1 (P1.3) on my products and at power up, the port is in high impedance, everything is ok.
Now we received a new reel of aduc7021 and this port (pin 1.3) now emit a glitch at power_up : 2V during 17ms with a pull down of 68Kohm…
Yes, this is possible.
The pin-out of the ADuC7021 is slightly different to the ADuC7020.
The following code will work for the ADuC7021:
GP1CON = 0x30000003;
GP3CON = 0x30000001;
GP4CON = 0x30000003;
PWMCON = 0x1; //Enables PWM output
Hi,Everyone , I got a problem in recently.
Why the same conditional of hard ware can not programming?
I try to remove and re-soldering ECU ,but it still show the message again.
I check circuit no short and open and also check clock frequency is 32…
We have a device that uses the ADuC7021. We have recently released the device to production. Now that large numbers of these devices are being manufactured, we are discovering that about 3-5% of them are not coming out of reset on power-up…
On the following parts, the exposed paddle is used for mechanical stability and should be connected to a large pad on your PCB but, this pad should not be connected to ground or any other track:
ADuC7019, ADuC7020, ADuC7021, ADuC7022, ADuC7023, ADuC7024…
It would be more helpful to send your complete project folder as a zip-file. As I assume, and experience proves it, that there is some kind of error in the exception handling of your project blocking the core and JTAG.
Hi, I was using the ADuC7021 controller. I was planning to use a RS485 driver to interface with an external device.However most of the 485 drivers dont have autodirection features that is it cant transmit or recive automatically. So i was trying to use…
I am using an ADuC7021 on a board that is available in two configurations: RS232 and RS485. I presumed that the bootloader would work on both versions of the board, as none of the documentation I could find said it wouldn't.
While the blackspace…
I encounter the same problem.
Are the new (shipped) parts ready for entering UART bootstrap mode?
MCU doesn't reply for ARMWSD.
Is there any method (besides JTAG, i havn't emulator tool) for…
