Hi,I'm almost new to the STM32 and have the following question: I'm triggering multichannel ADC1 conversions using timer 1 and storing the readings in a buffer using the DMA. It works fine until I configure ADC2 (which doesn't support DMA) to be trig...
The SetupSTMCUFinder-4.0.0-RC3 file can be clicked, and it seems like my OS tries to open / run it, but ultimately nothing happens. I remember having a similar issue with another piece of stm software, and remember running some command in the termina...
Hi everyone,I am using a STM32G474VETx chip and I have an issue with two peripherals being in conflict.I need to use the OPAMP1 input pin (PA1) for current sensing purposes. The OPAMP1 mode required is "PGA not connected" which automatically configur...
I have a PCA design which I'd like to support both devices with min configuration changes in the PCB dependent on the fitted device. I've made provision VACP1/2 options - either CAP or 0R resistor to VSS.
I load the program to the STM32H7B3IIT6 MCU, but when I close the circuit and open it again, the program inside does not work. I did not make any changes to the parameter settings.
What is the equivalent part for STM32F323VCH6 without having to redesigned the board?
I configured as follow the SDMMC bloc and completed the functions SD_read and SD_write using SDMMC + DMA.The problem is that HAL_SD_ReadBlocks_DMA returns Error before even starting the transfer with the errorcode 0x00000008. I really tried everythin...
Dear all,I've been trying to generate "LL_ADC_REG_TRIG_EXT_HRTIM_TRG1" with HRTIM to trigger a dual simultaneous conversion of the ADC of my STM32G474 based project.I use LL drivers so, to my understanding the code to enable the trigger on the HRTIM ...
