Re: ST7735 tft with a Bluepill STM32F103C8T6
My suggestion is that you try to get away from the prototype cables and weld everything with wires as short as possible on a perforated plate. Join strand by strand carefully, the arrangement you have it should work smoothly An old fashioned wire-wrap tool makes a much better connection that Dupont...

Re: "STM32 Mini F401" STM32F401CCU6
I have a few of those boards. For development, I keep switch #3 on and the others off. Pressing reset enables DFU mode and enables uploading a program. SerialUSB works without any issues. Enable Serial in the CDC options. To upload again, press reset to enable DFU mode. To see the pins available, se...

Re: Imposible to flash with STLink v2 key ( STM32F1xx and STM32F4xx)
Official STM32 v2.0 core with STM32Cube programmer makes this process easy. Sketch uses 10316 bytes (1%) of program storage space. Maximum is 524288 bytes. Global variables use 620 bytes (0%) of dynamic memory, leaving 130452 bytes for local variables. Maximum is 131072 bytes. ----------------------...

Re: Arduino IDE with MikroE M4 Clicker Board - Board Manager
What situation do you use the "CDC (no generic serial)" ? No generic serial on both the CDC and USART is my normal setting. This way, you are free to rename the serial ports to your liking. Here is a GPS example adapted from one of mburnette's projects: #define console SerialUSB // GPS mo...

Re: Bootloader Stuck 1EAF:004?
I agree: viewtopic.php?p=6984#p6984In my experience, with the non-Maple Mini boards, you have 2 viable options: ST-Link and using the internal serial firmware loader. The bootloader is just a nuisance.

Re: Need help with USB device MSC implementation
Secondly, If i managed how to do this, which library for SPI flash(W25Q64) should I use? Does it matter? The W25Q64 has a thorough data sheet showing the commands. I found a library for a W25Q16 at https://github.com/derekevans/W25Q16 . The commands in this library match the W25Q64 data sheet, so I...

Re: Crosstalk and sample frequency issues on a pressure sensor matrix
You may want to consider refactoring the code to use arrays of binary values instead of booleans. I would expect this to be much more efficient, as the arrays are simplified from two dimensions to one. const uint32_t outmuxChannel[] = { 0B0011111111110000, //channel 0 0B0011111111111000, //channel 1...
