I'm working on the SAI part to read the ICS4342MIC through I2S protocol, and looking for a way to stream a large amount of data from the microphone to the hyper ram (in memory mapped mode). The current available feature of the HAL_SAI_Receive_DMA fun...
Hi, I was very disappointed to note that STM32H743VIT6 is not pin compatible with STM32F407VGT6 in the LQFP100 enclosure. It would be nice if MCU F7 and H7 could replace F4, without having to redo the PCB board again.
Hi,The STM32H742xI/G & STM32H743xI/G website says:2× USB OTG interfaces (1FS, 1HS/FS)The STM32H742xI/G & STM32H743xI/G datasheet (DS12110 Rev 10 - 03/2023) says:Page 52:The devices embed two USB OTG high-speed (up to 480 Mbit/s) device/host/OTGperiph...
Hello everyone!I'm working on STM32WL55JCI7 board and trying to run ADC at the fastest speed (min total conversion time mention on datasheet 0.4uSec) and I don't receive this time.My configuration is the following:And to measure total time of convers...
I made an application that uses burst DMA on T2 of an STM32F407VET6 to create morse code pulses as a challenge for Burst DMA..My strategy is to write to ARR, the reserved register in between and CCR1 to make pulses of various width and duty cycle as ...
Hello Team,I debug STM32F405 on my custom PCB using nucleo board and STLink utility software.Now, I have added a digital isolator on my PCB , and the STM32F405 MCU is powered by the isolated 3.3v supply & ground of the isolator.Now, the Nucleo boar...
All these functions have one problem, let's say in this function HAL_UART_Receive_IT(&huart4, data,5);the third parameter is the number of transmitted characters.If you enter more or less characters in the COM port of the terminal than specified in t...
Hi I try to send a message to the CAN interface, use HAl functionHAL_CAN_AddTxMessage.But the message not send.I verify with debug that the interface is allwais in Listering HAL_CAN_STATE_LISTENING.Do you have idea what is wrong?uint8_t CAN_TX(int16_...
I found this problem with STM32L476 but I suspect it may be a general STM32 quirk.The manual does not list the minimum and maximum value of UART BRR register. While the minimum value of 0x10 seems to be quite obvious, the maximum correct value in the...
Hello everyone, I’m currently trying to use an stm32l4r9i discovery along with a b-cams-omv. I saw that this camera is listed as a supported product for this board, however, I cannot find an example project of these working together. If anyone knows ...
