Figgering Out the Differences

Hi Team I'm having great success using the Arduino IDE and STM32 boards from various sources; however one large bit of total confusion remains. I'm hoping very much that someone far cleverer than I can explain to me in a simple way. There are two different board manager entries that include the STM3...

Re: STM32 in Ham Radio

I've got the initial part of my next project up and running. It uses the STM32 blue bill board and is a controller for a RF linear amplifier. I have implemented a touch screen to select the frequency band of operation which in turn will switch inline the appropriate low pass filters. I have also des...

Re: xpt2046 touchscreen control with the ILI9341 TFT & Arduino

Thanks for the input; the support files for the touchscreen library state that it is for SPI2 - but I am not convinced. I've tried your suggestions but didnt get very far. I then tried another touch library which you initialise with an SPI instance whereby you specify SPI2 - it's called Serasidis_XP...

xpt2046 touchscreen control with the ILI9341 TFT & Arduino

Hi Guys I'm trying to use the STM32 "blue pill" board with a TFT screen with touch controlled by XPT2046. Its a fairly standard looking 2.8" module available in the usual places. I've got the TFT connected to SPI1 and the touch to SPI2 - I am trying to follow the information here: https://github.com...

STM32 in Ham Radio

I have a lot of project ideas and am now hooked on using the STM32. My first project has completed: https://youtu.be/AnpU52jWU4g I'm now working on control software for an RF amplifier, will use xpt2046 touchscreen control with the ILI9341 TFT. Software will switch low pass filters in and out of cir...

Re: No COM Port - STM32F103RC8T6

Thanks for the help. I have a much better understanding now. My fundamental issue was an out of date java RE generating a load of errors at Upload that was throwing me off completely. Now, I've tried your suggestions and will go back round it all again, but using one of the generic board types I am ...

Re: No COM Port - STM32F103RC8T6

Thanks for the pointer - I'm clearly not understanding something basic. How do I upload a sketch if I cant select a COM port - I dont know how to use the DFU device or USBSerial. Up to now I have been using the SAMD21 M0 clone boards without issue. you need to install a *sketch* with USB-serial sele...
