Now its done and working 100% All power pins are good and on spot. Also TX, RX works great! (COM3) on my PC.
Hey all im making a new PCB which i will use for ARM and PIC micros. Features: 5v Supply Via USB (SMD) 3.3v Supply Via LM1117 3.3 (DPAK) 1.8v Supply Via LM1117 ADJ (SOT223) USB to UART Via FT232RL IC (SOIC) All powered by one 5v USB connection. Also the USB is 3v for ARMContinue reading “Power ARM/PIC with USB UART”
Playing around with Microchips USB Framework. Basically from here i got the schematic and info. http://www.waitingforfriday.com/index.php/Building_a_PIC18F_USB_device Here are some pictures of my test board and a video of it in action. Just to also add i used the magazine paper to do this and it came out 99% perfect!!!
This is my single knob version of a etch a scketch. The PIC controlling the Rotary Encoder is a 18F4620 but smaller pics like 18F1320 can be used. and 16F pics also. The windows program was developed in C#(C Sharp) and it connects to the PIC via USB to UART connection aka FT232RL IC. TakeContinue reading “Digital Etch A Sketch”
Finally decided to make a PCB for this. I had the IC since last year heh… Installs fine an i see the LED light up on Sending data from PC to it… not tested yet. Once tested ill post schematic and code used to test it… Here is some code that seems to be workingContinue reading “FT232R RS232 to USB Converter”
