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...
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...
Hello Having real issues with the I2C DMA HAL code ???Is it buggy.... very likely from what i'm reading on the web or is there something I am not understanding ??I'm simply trying to read data back from a i2c flow sensor with minimal interruption to ...
Hi I am using STM32G030K8. as there is no TRNG options I am doing the ADC noise values to generate a 8 bit number.The MCU is supplied with 2.2V supply .I am using both mains and battery for my operation.However if battery is removed Im not gett...
I created a custom STM32F411 PCB. I can program it and blink a LED for example just fine. I also have a STM32 blackpill board which uses the same MCU. When I run some USB HID code it works fine on the blackpill but once uploaded to my custom PCB and ...
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 ...
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...
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...
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...
