Hello,We are currently using the STM32G070CBT6 microcontroller in one of our data logger devices, which operates on a three-phase power supply and is used in a transformer application. In our design, the microcontroller triggers a relay, and the rela...
I am trying to source a 12.288MHz clock for an STM32L433 but having difficulties finding something.The clock is required for I2S playback with a bluetooth receiver (BT401).I have tried using the internal MSI RC to generate the 12.288MHz clock for SA...
Problem When i call * USBPD_PE_SVDM_RequestAttentionI get a OK message response but the callback never gets called. * USBPD_VDM_SendAttention Curious to know if there's any good way to debug this? Current debugging stepsI have a STM32G0-Disco board...
Hi! I'm working on a Power Delivery Sink using an STM32G484RETx MCU. I managed to get SPR Power Delivery working without any issues, but I'm having trouble handling the EPR handshake.I'm using the latest USB-PD library from ST's GitHub:https://github...
Hello everyone,This is my first post on the ST Community forum.I recently moved from a custom 6-layer board using STM32H725IGKB to a simpler 4-layer board using STM32H723ZGT6. Both designs use an external OCTOSPI memory, with 50 ohm controlled-impeda...
I have swapped from a custom PCB-board with a 6-layer stack using a STM32H725IGKB, to another custom board with a 4-layer stack using STM32H723ZGT6 (simpler package).I am using an external OCTO SPI on both boards, but I have R/W errors with the 4-lay...
Hello everybody,I am trying to synchronize the ADC1 and ADC2 to work with center-aligned PWM signals in dual-simultaneous regular mode using DMA. My setup:PWM frequency: 5.2 kHZADC conversion frequency: 104/2 = 52 MHZIf I have 3 conversions per ADC w...
Can anyone tell me or direct me to a source that shows the minimum connections needed to power up and serially program a STM32F765ZGT6? (144 pin package.) I will be attaching the chip to a breakout board and will be using a St-Link Minie3. Any help ...
I am trying to do OTA programming modifications using the DUAL bank feature of my STM32U575 IC with 1Mbyte of memory.I have successfully done this when the program starts in BANK 1 and I reflash BANK 2. I change the User Option byte to OB_SWAP_BANK_E...
Hello everyone,We are having trouble getting tracing to work with our target at full clock speed and would like to understand why, we have an application running on STM32U575 @ 160MHz CPU clock, we also connected the J-Tracer to it using a connector ...
