Hello,In one of our new PCBs we use a STM32L476VET6. For the RTC we use an external Oscillator (shown in the Picture)The drive power is set to the highest level.In our setup, the RTC only works at room temperature and with no probe connected. As soon...
I have a situation where a USB endpoint stops working due to a control packet being NAKed in the handshake phase. I've traced the problem down to the STM USB stack setting DCTL.SGONAK = 1 in response to an INCOMPISOOUT event, yet in the case when it ...
Hello everyone. I am using an F411 and I cannot figure out how this is supposed to work. I enabled USB_Device in middleware, enabled USB_OTG_FS, and set up line encodings based on the default STM32 example, but when I flash STM (or step through with ...
I have noticed that in my Application project there is no SystemClock_Config() generated by CubeIDE so my guess is that these settings should be inherited from Boot stage. If that is the case, should I also not initialize XSPI interfaces, memories an...
Hello everyone,I’m working on an electronic design using the STM32WB55RGV6, and the final product cost is very constrained.I have a question regarding the SMPS components, specifically the capacitor C29 and the inductor L1 shown in the reference desi...
I am trying to develop I2S master using the NUCLEO-L433RC-P, but struggling to achieve a master clock speed for 48kHz playback.The I2S audio is working (using a MAX98357A I2S amplifier) and the master clock speed needs to be 12.88MHz (i.e. 48kHz x 25...
Hello,I am working on a custom mixed communication implementation using USART in single-wire half-duplex mode with TX-only operation, level inversion, and interrupt-driven transmission on an STM32G0B0 (RETx package).During testing, I observed the fol...
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'm using STM32H723ZG I want to know if a Timer's update event can trigger SPI transfer without any software interrupts.This is the problem
Hello, I wrote a program to test the CAN bus.In its current version, I am using standard CAN at 1 Mb with 8-byte frames.I transmit 16 frames with a 5 ms delay between each transmission.To identify the last frame in the block, I send a frame with a ze...
