Hi all, I just finished an RS485 network and am testing a node individually directly from com port with the following statement: serin 1,N2400_4,addrByte,serialByte All I receive is 2 bytes, address byte and command byte (simple protocol). The problem is i might also receive address bytes...

I am building a switching circuit using a PICAXE28X1 which drives 5 74HC595 chained ICs. The idea is to send a pulse to one of the 40 outputs and switch off immediately after the pulse. I intended to use the ULN2803A as an amplifier to each output point but in some older post on this forum I've...

If I use a picaxe 08M with no resonator and put the statement : SETFREQ m8 at the beginning of the code the picaxe should run at 8Mhz is it? Now i want the 08M to communicate with a 28X1 picaxe using serout at 08M and serin at 28X1, if i use SETFREQ m8 on 28X1 what resonator should I use...

I'm working on some project using 28X1 picaxe. The manual says that you don't need an external resonator to run this chip (picaxe_manual1 page 29). If i still use an external resonator (4Mhz) how do i know if the picaxe is running on the external or the internal clock? Is there a way to force...

I'm using an 08M to communicate serially with the picaxe. Each character i receive i output it as a byte to an HC595. I'm testing using hyperterminal on windows XP. The logic is that if i press 1 in Hyperterm the first LED is pulsed, if i press 2, the second etc. etc. The problem is that if...

I'm building a an 8x8 matrix moving display. I'm using 2 595 IC in the circuit one used for rows and the other for columns. I only have a single pause of 300ms between each character displayed but the display is so slow i can see column by column display. Any ideas please how i can handle...

Are there any limitations on the amount of data the lookup command can use? I have a table of 205 values but the lookup command only accepts up to 141 values. The values use are single byte values. Any idea what is the problem?
