![]() ![]() ![]() On old MD_MAX72XX.h was easy to change, like #define USE_PAROLA_HW 0īut on new one is are defferent, and all lines are in same place, don't know how change this. Problem with Librarys - rotating letters // Hardware SPI connection So, the best results gived me a downloaded MD_MAX72XX-main + MD_Parola (downloaded directly from arduino library ver. Right?įirst original MD_Parola-master and MD_MAX72XX-master not worked for me. And if I managed, then I can switch to TM1637. Good news that I remembered that I had 3x Max 7219 modules at home, so I connect 2 of them to play safe first. It says that not working with YUXIN timer (which is mine), and I am not sure is that says for Arduino project or some other project. In two weeks of searching and testing, I will write this post in as much detail as possible.īefore I start, please see this link: LINK. When you have that working, you can think about updating your display. I would suggest to begin using a software serial library to read the data from the timer and echo it to serial monitor. ![]() 'C': both hand-pads covered (overrides 'I', ' ', 'S') ![]() 'R': right hand-pad covered (overrides 'I', ' ', 'S') 'L': left hand-pad covered (overrides 'I', ' ', 'S') 'S': timing complete (both hand-pads open) ' ': timer running/counting (both hand-pads open) 'A': timer ready to begin, both hand-pads covered 'I': timer initialized and reset to 0 (both hand pads open) The payload is transmitted in 9 byte packets:ġ: command byte as ASCII character ('I','A','S','L','R','C' or ' ')Ĭhecksum: 64 + 0 + 2 + 5 + 2 + 7 = 64 + 16 = 80 = 'P' (chechsuk OK) This signal is converted to TTL level (5V/0V) by the MAX232 level shifter IC, so the Atmel microprocessor can understand it. The "stackmat signal" is essentially just a RS232 serial signal (1200 baud, 8 databits, no parity bits, one stop bit). It working with pulses which sending from timer? Is that hard to do with code?Īccording to a link on the page you linked to: ![]()
