This is not a question: I'm just contributing a working project that demonstrates an ST7735 TFT (1.4" in my case) driven by an LPC834, though I suspect an LPC832 might also drive it, if you optimize for space so the binary will fit in flash.
It uses the TFT code base developed by Michal Kozakiewicz, github.com/michal037, found here: https://github.com/michal037/driver-ST7735S
It uses LPC834 SDK 2.16.00 (2024-07-12), which seems to work a little better than 25_06_00, but I may have caused my own problems, there. 2.16.00 at least allows you to use the Peripherals tool to configure ADC, and SPI.
Uncompress the zip file, import the contents into a new project, and off you go. Hope this helps someone.
