ChibiOS Free Embedded RTOS

Thx, but STM32F1xx haven't periodic RTC configuration. As I understand MCU can wake up from standby mode my Alarm from RTC. But I my case don't. I rebuild code to wake-up (reset) by IWDG after calling wfi, but this is bad suggestions. Why RTC alarm not work? May be I must addition LSI configuration ...

Hello, all! I'm trying to build battery device with periodic wakeup by internal RTC or By Button press. Most of all time device in StandBy mode. And I need to wake up every 2 seconds do to some thing and return to StandBy. But Device don't waking up every two seconds, only by Button (rissing edge on...

Hello! Today I'am hase added ChibiOS as submodule to my project git. Aftre trying to rebuild from "clean" state i received error: error: 'USART_CR1_OVER8' undeclared Compiling board.c ../ChibiOS/os/hal/ports/STM32/LLD/USARTv1/hal_serial_lld.c: In function 'usart_init': ../ChibiOS/o...

The code is enabling channel 3?

Why?

What about in function?
palSetPadMode(GPIOA, GPIOA_BEEP, PAL_MODE_STM32_ALTERNATE_PUSHPULL);

Hello! I'm trying to enable PWM on TIM2_CH3, but can't. Yes, I know that ChibiOS use TIM2 for systemticks, but I'm writing FW for already completed board. What I have: ⋅ STM32F103RBT6 based board ⋅ No external OSCILATORS, only HSI ⋅ Buzzer on PA2 /* * HAL driver system ...

Hello. How to force host to enumerate my device? I use my custom board where only D+ and D- connected to USB, no VBUS lines. D+ pulled up to VCC via 1,5kOm. Now I has configured and build USB_CDC_F107 for by board, but when I connecting my device to host nothing happened. btw code generated by STM32...

Hello, Giovanni!

Any change re: isochronous endpoint support, or USB Audio Device class support?
I'm trying to make USB Microphone on STM32F103, but my device don't Configured my USB bus. Seem like usbInitEndpointI(usbp, AUDIO_STREAM_EPNUM, &epAudioconfig); have no effect.

Change code to: static msg_t touchWrite(I2CDriver *i2cd, uint8_t addr, uint8_t data) { uint8_t buffer[2] = {addr & 0x3F, data}; msg_t status = MSG_OK; i2cAcquireBus(i2cd); while ((status = i2cMasterTransmitTimeout(i2cd, sxaddress >> 1, buffer, 2, NULL, 0, MS2ST(10)))==MSG_TIMEOUT) { i2cd->state ...

Thx.

1. Now state LOCKED with TIMEOUT result but I sure that sometimes state was UNINIT.... Strange...
