Wire Bond Lengths Inside BGA

I am working with the stm32f407igh6 and need to account for timing in my layout. I have been unable to find documentation regarding the wire bond lengths inside the BGA. Are all the line lengths in side tis BGA the same length?

(Cubelde) I want to send uint8_t array and float variable with hal_uart_transmit. How can I do

I've tried things but I don't understand the exact logic l.

BPSK unmodulation only with STM32

hello all, for an internship I work on modulation / unmodulation BPSK.For the modulation I used a DDS drive by a stm32.But I want to know if it's possible to make the unmodulation only with STM32. I know we can measure the freq with it but can it do ...

Board-To-Board abstraction protocol (MUX, eRPC..)

Hi FolksI'm running a design where i have a sort "Expansions" board where all the Analog inputs and RS485 / UARTS port are located.This board is running a STM32F107 mcu.Then i have another board running a STM32F429NIH6 MCU, where we handle LCDs, ETH...

Hard fault for unknown reason

Hello,this is my functionvoid process_dds_ext_demod(uint16_t *inbufPtr1, uint16_t *inbufPtr2, float *in_phase_val, float *quadrature_val){ /*transfer DMA buffers to local Buffers-------------------*/ //transform values from int to float float ADC1_Bu...

Has anyone had any success generating sinusoidal PWM with DMA, on STM32G474? The same code that I implemented on a STM32F series does not work. Also, the ST example for this board, related to this topic, TIM_DMA, does not run as it has binaries missing.

STM32F7 SAI SPDIF TX channel status / frame count

Dear STM32-SPDIF-TX experts,I'm working with a STM32F767 on a Nucleo-144 board.Creating a sine, sending data at 24bit/192kHz via DMA / SAI 2B, everything fine.Filling the output buffer for SPDIF within the HAL_SAI_TxHalfCpltCallback() & HAL_SAI_TxCpl...

stm32G474 adc ground offset

Hello,I am having an issue with an offset on my ADC measurements. I am using the NUCLEO-G474RE, and I am using pin PA8 as the analogue input.When I measure an analogue pin, the value measured is a bit higher than the actual values. (Actual values mea...

STM32G4 Flash writes at BOR

Hello,We have currently moved on to the STM32G4 series, and we are now looking at a project where data will be occasionally written to flash under control of our own code. Of course, this exposes us to flash memory corruption during unforeseen power ...
