All, application note 10258 'How to use the LPC900 In-circuit programming (ICP)' shows the configuration of PCL and PDA pins for LPC935 to be at p0.5 and p0.4,...
All, PHILIPS claims in the data sheets for the LPC9XX family that the MCUs can operate at 2.4V to 3.6V. Have you tried to get one of them run at 2.5V? I've...
Hi there, You need to disable 'brownout detection' in DEVICE CONFIGURATION. Then it will work upto 2.4V, else it will hang/reset/stop-working at 2.7V. Hitesh...
Hi friends, I have two types of LPC922. One lot is LPC922F CCxxxx (TSSOP), other in LPC922FN CCxxxx. The verF is supporting multiple programming using ISP,...
The LPC936 utilizes the P05 and P06 pins for ICP indeed. I've already programmed over a hundred devices this way. Gertjan ... documentation. ... too?...
I've had trouble getting LPC935-936 devices into programming mode too. What worked for me was to set the reset-output pin from the ICPISPbridge program to...
Gertjan, which of the two you mentioned is what? For LPC935: PDA - p0.4 PCL - p0.5 For LPC936: PDA - ... PCL - ... p0.5? p0.6? Can you point me to an internet...
LPC936 is fully pin-compatible with LPC935. As far as I know this is not documented. ... already ... <maciej.wiatr@b...> ... programming ... to be at ... ...
Dear all, Ax51 CPU has bit control instruction that is CLR and SETB. LPC900 family have register are A,B,PSW,DPTR(DPH,DPL),SP,R0-R7*4 I confirmed the register...
Hello Gertjan, Thanks for the tip. I will go through bridge code and will try to implement. I tried using 10k pullup on p0.4, p0.5 and p1.4(reset); it improved...
... Dear yenOyuki, SETB/CLR opcode are suitable only in bit segment 20H-2FH and in SFR area for all address multiple of 8H ( eg. ACC B PSW Pn etc.) To...
Gertjan, you wrote in your former mail that P05 and P06 were used... for LPC935 it is P04 and P05... I suppose you meant P04 and P05, right? Thanks, Maciej...
Hello!! I want to put some asm code inside the main.c file!! Like: for(j = 0; j < 13; j++){ MOV A, #LOW display RLC A INC A } ... If it isn't possible... I...
... Check your C compiler documentation. it should tell you how to do this. ... There is no assembly instruction RLC @R0. RLC operates only on the accumulator....
Hello, I want to use the PWM to dim a LED. This led is connected with a 470 Ohm resistor to 5VDC. The controller is running on 3VDC. I want to set the output...
Mark, not 100% sure but I would think your assumption is correct that a pin that is associated with a function (UART, PWM) becomes push/pull. The open drain is...
Dear all, I want to use Timer0 of LPC938. So I try simulation by uVision3. When I selected [option] - [Device]tag "LPC938", I want it to move at about 100us...
Hi, the timers are identical on both microcontrollers. There is a chance that you slected 12 MHz external clock for one micro and the internal RC oscillator...

Dear Robert, Thanks you for your answer. ... Either microcomputer is the same setting that it is selected internal RC oscillator(7.373MHz). It is only a...
Hello, I am writing a bootloader for the P89LPC922. I use IAP lite to write to the program memory and this works fine. I want to reprogram UCFG1 (RPE) before...
Hello Mark, Before writing the UCFG1 register you have to give the CCP Clear Configuration Protection command (see example below). shift_out(WR_FMCON);...
Hi Mark, I agree with Pauls comments and feel that you have protected the configuration values with the config protection bits in the BOOTSTAT register. These...
The user's manuals suggest the pwm pulse width uses the timer clock. This implies p-clock or external clock is used to determine the pulse width and pwm...
Rod, I'am trying to compile the LPC935-PROG on windows using Mingw but the popt.h file wasn't with Mingw. Was that file part of your linux distro? I tried...
John, You are going to need popt for mingw I know when I did this I went to a lot of trouble to get this working. I ended up downloading popt and then making...
