Code could look like this. Not tested, not embeded in code, specifically in the Picaxe 20X2 the lack of RAM/Variable space would be felt if you do want to embed. Probably worth looking at 28X2. Thierry

I've ported the AXE133 software from the original 18M2, which I 'overclocked' to 32MHz so it receives at T4800 (see above) to run on a 20X2, which is larger, faster and a bit more expensive (3 vs 2 GBP). See if I could run it at 64MHz and T9600, ... yes it does. And as I expected T19200 was too...

I've now ported the BPM085 program from Terry Simmich to a 20X2, which was relatively straightforward except for the smaller RAM size compared to the 28X2, so I had to squeeze for a little bit of room. Plus added Humidity reading with a DHT11 unit using an external 555 timer IC, as described...

Joel I've slightly adapted the AXE133 firmware so the 18M2 runs at 32MHz and serial communication at T4800: errorfree. I've used this 18M2 serial-LCD back-pack with the OLED16x2, but also with different LCD20x4 with minimal/zero code adaptations. I have also tried at T9600, but not hard...

Simmicht, thanks for this post on BMP085 calculus with fractional math. I've used / adapted it for a Pressure and Temp reader with a serial OLED/LCD unit for readout (AXE133Y). The following adaptations are made: turned off 8x oversampling by hardware (OSS=0, or '1x' oversampling) introduced...

Example program connecting a MAG3110 3-axis magnetometer to a Picaxe 08M2. The Mag3110: has an I2C interface is very sensitive (0,1uT resolution, while the Earth's magnetic field is 50uT strong around here (and pointing almost straight down, about 65-70 degrees downwards, didn't realise that)...

srnet Here's the program on a standard 08M2, default freq: do serout C.4, T2400, ("UUU") pause 1000 loop It resulted in: As far as I can see, that's 2 stop bits, or a delay between a stop bit and the next start bit with approximately the duration of a stopbit. Thierry

Hi, I'm trying to set-up some serial comms with Picaxe M2's. Works like a charm between Picaxe modules/chips. However, I'm having trouble with having Picaxe 18M2 (inside a AXE133Y 16x2 Serial OLED module) receive serial signal from another family (Arduino, in this case a Duinomite). Having...
