I look at the documentation for the BX-01 and then I go to Amtel's site for more hardward information and I just seem to get a bit confused. First of all, Amtel does define the BasicX microprocessors as reduced instruction set [RISC]. The whole idea was to eliminate the complexity of Assembly language encoding. But Amtel's AVR RISC has 100

Hi I have been doing some circuits with the BX-35 chip and one day I noticed that the onboard programmer I use (the suggested bx35 hookup schematic) didn't work well. Most of the times I got a EEPROM Checksum error, which puzzled me a lot since I have been using the same design over and over. After a different test I noticed that the chip wasn't anym

Hi my friend T. Andley gave me a reference to this site re: Bx-24. Him and I do hacks with the robosapien robot. I just recently purchased a BX-24 Dev kit, along with Robodyssey Hack- A-Toy(Robosapien) kit which feature the BX chip and a "portable" board to apply to Robosapien's back picture's and my work can be found at -

I have 4 new DS1302 chips and 4 new 32khz watch crystals intending to make a persistent RTC for my BX35 project. Problem is that after finally connecting all the stuff together on a breadboard and programming up a simple test routine I do not get healthy results. One of the DS2302's will count up the seconds register but appears to take from 4 to 8 (variable

Hi, I thought you might be interested in the newest project article on my website called "Building Circuits for Stripboard using EAGLE". This article, first published on 13 June, 2005 describes the process I use for building circuits on stripboard (aka Veroboard in Europe). I use EAGLE to draw the schematic and help design the circuit layout

FYI, according to engineers at an ATMEL seminar Tuesday, the quoted write cycle endurances of Flash memory in the current AVR parts (in particular, the ATMega169 was being discussed but the BX-24p's ATMega8535 is included) of 10,000 cycles, and 100,000 cycles for EEPROM, are very conservative. Typical endurance for Flash is 100,000 cycles and even one mill

Hi Just a thought, would it be possible to upload the binary file loaded on the BasicX ATMEL uC flash memory and use it with Proteus ( http://www.labcenter.co.uk/ ) AVR Simulator? Proteus says that their program can simulate any native binary file for the AVR. Then using the BasicX code generate

I'm PWM'ing a DC motor with Timer2, so it's 8-bit PWM, which I'm running at 450Hz. 30:1 gearing brings the output shaft to 1RPS when the motor is at 1800RPM. I'd like the 1RPS to be as accurate and stable as possible. Currently, the motor approaches 1800RPM but, due to the relatively large PWM steps, hunts about the target speed slightly as code alternatel
