Hi,Are there any APIs available to read the base frequency dynamically on the RC-868 RF module?I noticed the S2LPRadioGetFrequencyBase API in the S2LP driver. Are there any additional APIs for this purpose?
My target is a 144 pin version of the STM32H5.I would like to implement both a JTAG and a FMC interface.More specifically, a 24-bit muxed-PSRAM.And I would like to output the Byte enable signals.However on this package size, there is only one possibl...
Hello, I’m working with an STM32F446 and have configured GPIOB pin 12 as an EXTI input. After initialization and before entering the main while loop, I call a function that blocks program execution(what I mean by blocking : I have a test that stands ...
Dear ST Team,我用usb转ttl单独对4g模块发at，回复消息是正常的，单独模拟给单片机发数据，回应的数据也没有丢字符，就是4g模块跟单片机之间通信的时候存在问题When I use a USB-to-TTL adapter to send AT commands to the 4G module alone, the responses are normal. When I simulate sending data to the microcontroller alone, th...
In the lower-end STM32L4, covered by RM0394, SRAM is partitioned into two parts, SRAM1 and SRAM2.SRAM2 (besides being "special" in that it has ECC and automatic erase facities), is mapped at both 0x1000'0000 and at the end of SRAM1 in the 0x200x'xxxx...
Hello, I want to design a PCB with STM32H743VIT6 MCU. But I am not sure how can I choose crystal and capacitors properly. In STM32H743VIT6 datasheet there is one section about this topic;according to this information should I take the Cstray value as...
Hello,I'm new to this STM32 products. We designed custom module with STM32F103CBT6TR. We are facing issue with serial boot loader.I'm using CH340 UART to USB converter module. CH340 MOD TX --> Our Module's RXCH340 MOD RX --> Our Module's TXCH340 MOD ...
From the ES0335 errata there are two errata that look pretty significant for dual bank boot (which I'm planning to use as the basis of field firmware update):2.2.8 Dual-bank boot not working when the boot in flash memory is selected by BOOT0 pinDesc...
I have an I2C device that only operates with 1.8V logic (Pins are not 3.3V tolerant) that I want to connect to the STM32N6. I don't want to add an I2C redriver if I can avoid it. I want to keep as many of my I/O pins on the STM32N6 powered from 3.3...
