Dear Forum, I was curious to find out how to read the DS18B20 temperature sensor without using the wellknown and easy-to-use READTEMP command. So I took the data sheet and started reading. However, I gave up because I did not understand most of it (I did understand the data sheet for the ADS1115...

Dear forum, it’s not my habit to bother the forum, unless all other sources are gone. The program below sends three short text fragments in text boxes to a Digole Touchscreen, after the first hit. The program does that in the interrupt-mode. That works OK. After a second hit, the program checks...

Dear Forum, when I use (merely as an example) the command hi2cout 0, ("SD",1) (after HI2CSETUP) ,I can send this command to my touch screen (Digole 320x240 touchscreen). That works OK. As I understand it, the command hi2cin 0,(B0,B1,B2,B3) should read a series of bytes that are send from the...

Dear Forum, and especially member MEMRAN, I’ve an MPU6050 (ITG-PMU) that works with an Arduino, even as a compass. BUT: I’m not an Arduino fan and I only used the Arduino to test the MPU6050. To this end I borrowed the info on the site...

Dear forum, I'm using a 28X2 to send a number to a second 28X2, using the well-known DORJI transmitter/receiver. Extremely straightforward. It's just a test set-up to check the reliability of the transmission. That works OK, no problems here. BUT; I want to check the reliability of the...

Dear Forum, Just an idea, but it would be nice if it works: Many Picaxe users would like to have a very stable, reliable oscillator frequency for their Picaxe. It is of course known that it is possible to use a crystal as an external resonator instead of a standard resonator. However, even...

Dear Forum, I use a Picaxe 40X2 + two stepper drivers DRV8825 to drive two stepper motors, and that works perfect. The two stepper motors will in due time be driving an x-y table, for use in a simple 2D/3D-plotter. However, I have the following problem: if I use the sin and cos function in the...

Dear forum-members, In order to read the data from my clock chip DS1307, I use the program below, including a 5-line conversion calculation (the sub called "reken") to change the clock data from hex to dec. The program runs OK, so that's not the problem. My question now is: is there a...

Dear forum, I never experienced communication problems (serin/serout) between two 18X chips or between an 8M and an 18X chip, but then I bought a 20X2 that did not communicate with the "old" chips. I blamed the calibfreq factor and forgot about the problem (all te other functions of the 20X2...

Dear all, I took out the IR-camera from a Wii-mote remote control and used it to build the stand-alone camera that was made by "robotfreak", seehttp://letsmakerobots.com/node/7752 The reason: this would be the long sought-for solution for our robot location problem: the camera on the ceiling...

Dear all, I've gone through the answers to Diepenpj's recent spiin/spiout questions, but I still miss something: I'm using a 40X1 and I want to use spiin/spiout in combination with an LTC1298 (shiftin/out much like Diepenpj's ds1620). The spiin command is (roughly) "SPIIN...

Dear Picaxe community, the following program (see below) works perfect with my two 18X-boards, but neither with my 28X board nor my 28X1 board. If I run the program at setfreq m8 (18X) and adapt the baud rate it also works fine (better, because longer recognition strings can be read). If I run...

Question to (I quess) Technical, or to Techsupplies: I recently bought two LCD firmware chips (FRM010) and I tested one of them. It gives all kinds of odd readings, and I wonder if I'm facing the same problems that Markey26-UK experienced. Checked all connections three times, no lose contacts...

Dear all, I know that the question has been asked before, but: any idea when the new x2 version of the Picaxe 28 and 40 will be available? And a second question with regard to the 40 MHz clock speed: is that compatible with the standard buad rates, or does it have to run at 36 MHz to be...

Dear all, I recently downloaded the program StampPlot, that provides easy ways of plotting graphs from the Basic Stamp. Works very well! It also works well with the Picaxe, as expected. There is however something I can not solve: if the Stamp sends: "debug IBIN8 val,CR" then Stampplot...
