ADC with DMA Half Conversion complete and Conversion complete callback not aligned.
Hello,i set stm32f103c8 adc1 at 12mhz . Main clock is 8Mhz * 9 = 72Mhz.i use ADC_SAMPLETIME_7CYCLES_5 so 12.5 + 7.5 = 20cycle = 600ksps.i set dma circular continuous mode with 1000 element buffer.i can receive half and conversion complete interrupts ...
why adc is slower at 72mhz compared to 56mhz ?
in reference there is such information ; STM32F103xx performance line devices: 1 μs at 56 MHz (1.17 μs at 72 MHz)why does it take longer in 72mhz ?
STM32L072CZ. NVM programming example project crashes.
Project based on "01_NVMEraseProg" from the "STM32L0xx_Snippets_Package_V1.2.0" crashes.Below is a source code to erase/write 100 flash pages. Code crashes 9 time out of 10.int main(void){ uint32_t addr; error = 0; SysTick_Config(2000); /* 1ms con...
spi master slave communication
Hello every one,I am trying to communicate spi master and slave with two discovery boards In my case stm32l152rc is master and stm32f407vg is slave..When i am sending from master to slave it's receive complete data but when am sending slave to maste...

Hi,Masterplatform:stm32f030c8 and stm32f103vc I want to download firmware from the FTP server through the GPRS module, perform local firmware upgrade, ask if there is any FTP client information document or demo, thank you very much! Please forgive ...
How to properly set up external crystal for NUCLEO-L073RZ?
I am using the NUCLEO-L073RZ development board. When looking at the documentation, it seems that the STM32 MCU (U5) on this dev board uses an external HSE clock signal from the programmer MCU (U2) on the top portion of the board. This MCU (U2), in tu...
"Cache New" Nut My_system_stm32h7.c file for Clock config: 4 Lines too much
Sorry, I just recognized that in the file I appened to the "Cache New" Nut question, I kept 4 test lines to get this "Code 32 alignment" done before the for wait loop ... .But this does not work ... this will unfortunately be refused by the compiler....
Why transmitting data in STM32 I2C slave is not working
I am using STM32L4R5ZI as a I2C slave. From I2C master I am getting first command and On my slave device I am sending the response but the slave code hangs there(and it makes my master device to reboot automatically). Please provide the necessary inp...
How to communicate MCP39F511 Power Monitoring IC with STM32 to read RMS current and voltage values?
I am trying to read the RMS current and voltages values from a MCP39F511 IC by using STM32, I was wondering if there is anyone who is also working with MCP39511 IC and has a way to read those RMS Values from MCP39F511 by using STM32!
