Is it possible to use a AXE132 to drive a Hitachi HD44780 display, with serial input? Thanks, mas11

Is there a way to check and see if a signal is coming in from the receiver on a 433mhz system. I would like to know if the transmitter is sending a signal or not sending a signal. If not, then I would like to have a message displayed on the lcd stating that there is no signal. I finally got the...

I am once again having trouble measuring voltage. I have had good success with 20 volts but am having trouble with 9 volts. Code is enclosed below. I have search the forum for answers but I can't seem to get any of them to work right. Probably my fault because I am very poor at math. I am...

I recently purchase a 4x20 serial LCD#117 from Modern Devices and am having trouble getting it to read data. The start up screen comes on OK but when it reads the data, all I get is a bunch of X' at random locations on the display. I think I am not writing the code properly. I contacted Mr...

Can anyone tell me why when using a 14m2 chip and the pwmout command(b.2,25,52), I should get 38khz, but I get 154 khz instead. I am using the chip in the multimode condition. So I am using the start0 command at the top of the code. As loug as I don't use the start command, I get the 38khz...

Hello All. I am back after taking advice from the members on trying to light a few LED's before trying any harder programming. So I have been flashing LED's and making them blink, turning them on and off, making sounds and so on, but I am having trouble with the count comand. If you remember I...
