Hello, I looked at AN5419 and configured the stm32H725igk6 power supply circuit as shown in the following figure, but the external osc does not work and the st link is not connected to the MCU. Is this product a model that must be configured using S...
Hi !I'm trying to configure the ADC1 to 7 ranks conversion and a GPDMA1 channel (0) in "Standard Request Mode" to transfer the ADC data into the memory.First, I've configured the ADC without GPDMA channel, and it worked fine (Polling mode, no interru...
Hi there!I was trying to emulate eeprom using flash memory. I am using Nucleo-F030R8 board. I was able to program flash 2 times (0xF055 was the test value):however I cannot reproduce it anymore and whilst trying to program I get PGERR.Uploading my co...
Hello,There is a typo in Table 14 in page 153. It is mentioned in different places that STM32H7B0 supports OTP but in this table it is not mentioned!Could you please confirm that this variant supports OTP?Thanks,Ayoub
i am Initialize UART2 and timer1 then my timer interrupt and UART2 interrupt in working fine but when i set priority timer first they do not set why? void main(void){NVIC-Set-Priority(TIM1_BRK_UP_TRG_COM_IRQn, 0);NVIC-Enable-IRQ(TIM1_BRK_UP_TRG_COM_...
Using UART in Receiving Interrupt mode, I want to update various global variables values from console like Putty. Something like first send the opcode and then value. Please suggest if any sample codes available. I am relatively new to programming w...
