Resolved! Switching time for mux on Opamp

Various STM32 products have opamps that have a mux in front of it.Ex: STM32G4, STM32F3, STM32H7 series, etc.If I change the mux input setting using the control status register (OPAMPx_CSR::VP_SEL or VN_SEL), how long does it take for the mux to switc...

FMC peripheral memory

How far from FMC shall we place memory device. I have stack-up design(3 boards) in which MCU is on top board and FPGA is on bottom board. I need to map FPGA to FMC. Are there design consideration for routing FMC signals for such board to board commun...

I cannot understand this function "Cunstom_STM_Update_Char" regarding aci_gatt_update_char_value in BLE P2P template example.

I'm following the P2P template example and I found that to send data using BLE, the example uses the Custom_STM_App_Update_Char function. However, as I know the update API is aci_gatt_update_char_value. So, I'm confused because the Custom_STM_App_Upd...

HAL SMBUS on STM32L071xxx, how to set up correctly

I configured I2C SMBUS in cubemx and reimplement HAL_SMBUS_MasterTxCpltCallback, then I called MX_I2C1_SMBUS_Init() and HAL_SMBUS_Master_Transmit_IT(). After that i had no any events: not called callback and no any data transmited. In fact on sda and...
