+===== transmitting =====
+==== 318LIPW1K ====
+The 318LIPW1K can be flashed using a PICkit2 micro-controller.
+The {{:megacode:318lipw1k_schematic.pdf|schematic}} describes how the micro-controller is connected.
+A pin header can be soldered on the board:

+{{:megacode:318lipw1k-header1.jpg?250|}}
+{{:megacode:318lipw1k-header3.jpg?250|}}
+The firmware is available in [[https://git.cuvoodoo.info/kingkevin/megacode/tree/master/pic/318LPW1K-L|git]].
+You can define the code to transmit in [[https://git.cuvoodoo.info/kingkevin/megacode/blob/master/pic/318LPW1K-L/eeprom.asm|EEPROM]].
+==== ACT-34B ====
+I de-soldered the PIC12F508A micro-controller and replaced it with a pin compatible (slimmer) PIC12F1840:

+{{:megacode:act34b-replace2.jpg?250|}}
+{{:megacode:act34b-replace3.jpg?250|}}
+The firmware is available in [[https://git.cuvoodoo.info/kingkevin/megacode/tree/master/pic/ACT-34B|git]].
+The two right buttons are used to send codes defined in the source.
+I planned to use the two left buttons to brute force codes but did not finish the implementation.
