I'm getting some weird I2C behavior with a GY-87 (MPU6050, HMC5883L, and BMP180 sensor)

Whats happening is when I probe the WHO_AM_I register on the MPU6050 I am getting a weird response of 0x72 instead of 0x68. This does not happen on a generic MPU6050 only board. Any ideas? the code in question is simply "HAL_I2C_Mem_Read (&hi2c1, MPU...

Hi I have a custom STM32H743 board with FMC nor flash M29W128GH70ZS6, and I want to run code on this FMC nor flash.I noticed there is anexample project in STM32Cube_FW_H7_V1.11.0\Projects\STM32H743I-EVAL\Applications\ExtMem_CodeExecution\ExtMem_Appli...

STM32L562CEU6P locks up and requires power cycle (NRST not working)

I created a development board for an STM32L562CEU6P (P = SMPS part) which contains a 1.2V step down regulator for the externally-provided Vcore, and it also has a USB->serial converter (for various reasons I didn't want to use built-in USB) and an ST...

Hello, the STM32F030C8T6 chip I recently bought has repeatedly reset after the burning program, and can only be burned once. After the first successful burning, after the reset by external keys, the chip reset pin will continue to output triangle waves, r

Can anyone provide some reference or sample regarding i2c slave bitbang implementation in stm32

how can store different channels of ADC in a array of two dimension used on DMA ?

I am using stm32F030R8 Nucleo, my program reads three adc channels. Below I am showing the image. I don't find how to set ADC or DMA to get every ADC channels converted directly in a array like this uint16_t adcData[ADC_CHANNELS] BUFFER_SIZE]ie:adcDa...

STM32L072RBT6 - Define PC9 as AF2 for analog output

Hi, I am trying to Define PC9 as AF2 for analog output. After defining, the output keeps high. How can I define it as "TIM3_CH4" not" USB_NOE"?It could be the reason getting HIGH.Thanks!Jason
