Can STM32 able to replace an old peripheral that required 8-bit parallel data bus and communicate between 8051 MCU. We can't modify the 8051 MCU and we can't use FPGA too. I know FSMC is very close solution to my case but in my situation, the STM32 i...
Hi everyone,I am trying to use CubeMX and the HAL library to get two STM32F411E discovery boards to communicate with each other via SPI. In a first step I am simply trying to configure the master correctly. I want to drive the NSS pin of the slave wi...
Hey guys, just having the hardest of times changing clock frequency to 80MHz for the system clock and 43MHz for the ADC clock. Every time I try it seems the writing function to registers gets disabled such as RCC->AHB2ENR trying to enable GPIOA and A...
Trying to setup communication between stm32f407VG discovery and nrf24l01 via SPI. It looks like reading data from registers is going fine, but there is trouble with writing to them because, doesn't matter if i write something to register or if I don'...
Hello,I'm not able to enable MR under-drive mode in my STM32F779NI chip.The exact problem is UDRDY is not getting set -> Line number 39 to 43.Below is the code snippet. Any suggestion would be very helpful. Thanks in advance.int main(void) { /* Add ...
Hello ,I would like to get some examples for WFE based sleep . In stm32cube examples, i see that most of them are like WFI based examples. Request someone to help me with this information. Thanks in advance.Regards,Vinoth
I would like to perform DMA based memory to memory transfer between cores with interrupt generation on Transfer Complete. To start of with the project i used Demo code (STM32Cube_FW_H7_V1.7.0 -> Projects -> NUCLEO-H745ZI-Q-> Demonstrations) added mem...
Hi,I want to use 3 (and after 5) ADCs to be triggered with the same trigger (TIM3) and to receive an interrupt when the ADC conversion is completed, with DMA. I assumed that if the 3 ADCs have the same trigger and the same configuration, when one of...
After playing around with CubeMX for a while and looking at the generated code and at the SLA0044 Ultimate Liberty Lisence where ofcourse the question comes to mind what ultimate liberty... really means while there is a license that comes with it......
The problem I am having is the flag in the HAL_ADC_ConvCmpltCallback() function is never set, so the "if" statement in my main while loop is never entered.
