Re: IR receive library.

Do you use any Arduino IR transmitter/receiver kit like this one ?

Re: My custom boards (STM32F030K6T6, STM32F103VET6, STM32F405RGT6, )

Nice boards !

I know it's a matter of cost, but maybe you could add a CH340E or CH330N to the 030K6 board because that mcu lacks usb hardware. The USB-to-Serial converter addition could also be used as a firmware uploader.

Re: STM32 HID Bootloader - Sumup

STM32 HID Bootloader (HID-BL) is updated to v2.2.2 It supports F103 High Density (HD) devices. The difference that affects HID-BL is the Sector size (Page size) Low and Medium devices have a page size of 1 KB. High-density devices have a page size of 2 KB. If you want to burn HID-BL to an HD device...

Re: Bluepill - smoked!

According to the manual, the STM32F103 works from 2 to 3.6V. Normally, the STM32 should be powered by 3.3V. 4V or more may cause permanent damage to the device. STM32_Absolute_Max_Ratings.jpg There is also a 5V pin on the Blupill board, but the AMS1117-3.3 voltage stabilizer needs an input of at lea...

Re: STM32F401CCU6 LQFP100 (!) development board

It seems that STM32F401VB, STM32F401VC STM32F401VD, STM32F401VE MCUs have LQFP 100 package

As Just4Fun said, the STM32F401CCU6 is a QFPN 48 package device
I bought recently this STM32F401CCU6 board

Re: STM32 HID Bootloader - Sumup

I chose Java because of its portability between operating systems.

The Java program edits the main bin file and saves the patched .bin file with a different file name.

The new .bin file can be used as usual, e.g. with st-link.

Re: NOT STM32duino ... we are much more broad

Well, this forum started as a follow up to stm32duino.com when it was read-only at that time. Primarily, the purpose of this forum is to help people ask questions about STM32 micro-controllers. The truth is that STM32 MCUs are really great, but there are so many other MCUs on the market that they ar...

Re: STM32 HID Bootloader - Sumup

Nice ! The next version of HID Bootloader that is almost ready will only have one bin file for all F103 cards. The number and polarity of the LED, DISC pins are set by using a Java program I wrote. By default, the LEDs and DISC pins are not set (not used). More specific, the .bin file is patched bef...
