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...
Hi, Please share pointers on interfacing 32Bits RAM along with STM32H750XB MCU with QUAD SPI External Memory and 8 MB Frame Buffer RAM on STM32H750XBRAM - IS42S32400TFT USED - 1024x600 at 24 bpp and or 1024x800 at 16 bpp at 60 + FPSAre These Set...
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...
I have a question regarding voltage level I/O compatibility for STM32 MCUs. The sensors providing analog output within a 0–5V range, while those with digital output at either 0V or 12V. Although some GPIO pins on the MCU are 5V tolerant, they are sca...
