I want to interface to an existing RS-485 bus where the 9th bit (normally reserved for parity) is set to 1 for the first two packets of each frame (as an addressing mechanism) and then cleared to 0 for the subsequent "data" bytes.If I set PCE=0 in r...
I need the callback, to clear the cb4.DMA_Active flag and update a pointer when it finishes. I cannot step through it because it starts sending data over and over as I step through it and does not call the callback. First time msg points to "12345678...
I'm having trouble with my IAP erase and write of Flash in my custom bootloader. I need to overlap comms activity with Flash erase so comms doesn't time out, but despite attempts to force the bootloader code, ISRs and vector table into SRAM, my suspi...
In my project I write some bytes to the internal EEPROM of a STM32L152CB. While running a debug session I can verify that the data has been stored correctly. At power up I read the EEPROM data and store it in some variables. As the MCU is configured ...
In code, we do not have call for changing RDP but we have a logic to reset IWDG_STOP bit after wakeup from sleep mode. We are facing this option byte corruption problem when battery drops below 0%. (We do not have HW support for cutting off power for...
The "operating temperature range" is specified as +85 deg. C high limit.Does this really mean the MCU can operate with an ambient temperature of 85 C ? Only the maximum junction temperature is specific in the data sheet.
Hi Folks,Greetings!At my end have a STM32G474 HRTIM output driving a MOSFET gate driver such as IR2110.In some weird cases encountered, when the MOSFET blows up, it takes away with it thegate driver as well.Not in all cases, but in some situations, I...
I am using STM32H753 MCU. I generated my code using STM32Cube. The UART is configured to work on interrupt, baud rate is 19200. I sent 'A' many time but most of the time I am receiving "C1" in hex instead of "41" ('A' in ASCII).When I analyzed the da...
I wrote twice in here that I was going to get the board from mouser and infact I ordered the board just becasue of this webminar. I wrote it twice to be sure... and now I just received a message that my seat has been reassigned? what? is it supposed ...
