I am starting a very interesting project...
50x32 PCB
ATTiny85 with ISP programming interface
nRF24L01 radio board interface
2 x 3.6V rechargeable cells with charging circuit from a solar panel
Software to drive differential DMX512 and WS2811 LEDs directly
This board will have many uses (standalone programmer etc)
I shall also be using this to test out my self-searching radio channel software !!
so far so good !!
Although I cant get 2 pins free to drive DMX differentially, so I am having to use a driver chip !!!
I only have enough ram at present to output 210 channels of DMX,
Not tested the solar/reachargable side yet
Ready to test WS2812's !!
I have found that the non-antenna version of nrf24l01 makes a good TX board, and the board with the antenna is great for a receiver, so far I have the TX placed 3 floors and several brick walls away from RX and the throughput is extremely good
