I am trying to flash a chip on a PCB. Right now I just have it toggle an LED. Sometimes it connects, but does not toggle, only stays lit. After power cycling, it does not even light up, it just stays off. Is there something i am missing, perhaps in t...
Hello, I am trying to write and read from stm32f105 to an eeprom 93AA46A, using Full-Duplex Master. To write into the eeprom, I am using following code:void EEPROM_WriteEnable(void) { uint8_t cmd = EEPROM_CMD_WRITE_ENABLE; //0x98 EEPROM_CS_H...

Posted on February 11, 2015 at 13:01Hi, Does anyone familer with Low cost microcontroller with 16bits ADC (below 1.5$) ? Thanks
I used the code below but not working , did you find the solution ? void SetPinTristate(GPIO_TypeDef *GPIOx, uint16_t GPIO_Pin) { GPIO_InitTypeDef GPIO_InitStruct = {0}; GPIO_InitStruct.Pin = GPIO_Pin; GPIO_InitStruct.Mode = GPIO_MODE_INPUT; // Swi...
Does anyone have PCB Wiring Guidelines for the STM32H743XGH6?
Hello, I am trying to write to the option byte area of an stm32u5g9vjt6q using the built in bootloader over the canFD protocol. I have verified I am able to erase and write my programs to flash over canFD using the built in boot loader so I know tha...
Hi ST team,I'm implementing DShot protocol with Timer + DMA. I use 4 PWM channels to generate control signals for ESC. Timer and DMA's parameters are same for all PWM channel. But PA3 (TIM2_CH4) does not work the same as other PWM channels. It only t...
Hi Everybody! I confronts a very interesting problem at my project. Details above:Hardware: NUCLEOG071RBAttached the IOC configuration. Control the SPI CS pin by software. I got small 4-8us signal spikes all GPIO, SPI, I2S pins. SPI and I2S powered ...
Hi, I want to go to sleep/stop mode with STM32 and wake on interrupt. After last interrupt it should wait for 10sec and go back to sleep. But I see an edge case where interrupt could occur just before going to sleep/stop mode.How do I handle interrup...
