0 Replies and 1436 Views Touch-screen controller and interrupts.  1436  0 Started by  Deleted User I've written a touch-screen controller driver for the Linux kernel. It seems to work. BTW: > The CE has P/N 80000113-057 rev e04. > The CPLD reports revision number 0x20a I haven't been able to determine the role of the PIRQ bit. When I clear the bit, the touch interrupt bit goes low. However, if I leave PIRQ high, the touch controller appears to work correctly. The documentation states that the touch interrupt pin has to be driven for correct operation of the touch cont...

7 Replies and 1540 Views CPLD I2S transmits 8 bits per channel? Or 10?  1540  7 Started by  Deleted User According to the documentation, the CPLD will shift 10 bits per channel, bits 15-6. The output I'm seeing on an oscilloscope shows that there are only 8 bits transmitted per channel. My audio data is a bonafide 16 bits per sample.&91/b&93

18 Replies and 1851 Views is on board flash booting possible/feasible?  1851  18 Started by  tozyagcilar Hello all, I am wondering if it is possible to boot linux from internal flash(on-board, 8 to 16MB) instead of tftp or CompactFlash. How hard would this be and what needs to be done I am assuming that the two partitions created on CF should somehow be created on the on-board flash also, since the kernel will be looking for the rootfs. How can this be done if at all Is there a way of doing this without partioning Any suggestions/ideas/opinions are welcome... Thanks! Talat,

4 Replies and 1476 Views Display "Ghosting" on LCD3.5-QVGA-10 LCD Module  1476  4 Started by  Deleted User Hi I'm currently in the process of driving LCD3.5-QVGA-10 LCD Module via the SDK-LH79520-10 application board. The problem i'm seeing is that there appears to be display ghosting on the lower half of the display, ie, any bitmap image that's drawn in the upper half of the display replicates itself in the lower half. Bitmap images are drawn to the display via a frame buffer that i've configured the UPBASE register to point to. I'm not sure if this is related but writing to the first 960 locatio...

3 Replies and 1540 Views Flash Programming  1540  3 Started by  Deleted User I'm trying to program flash, but to do so, it appears I need to set the VPEN pin high on the flash part. The VPEN signal can be traced back to the CPLD. Can you give me some information on how to control the CPLD to raise this pin.

2 Replies and 1412 Views Hitachi Colour STN LCD Problem  1412  2 Started by  Deleted User Hi I'm attempting to connect an Hitachi, 320*240, SX14Q004 colour STN LCD (8-bit colour mode) to the 79520 starter kit but with only partial success. The LCD appears to be semi-working, ie, it can flood filled with various colours but the positional accuracy of individual pixels is not quite right. Looking at the signals, specifically, Frame, Load and CP, reveals their quality to be very poor - approx 25 noise with the CP signal being particularly bad. Could this effect the positional ac...

6 Replies and 1533 Views How can I escape the boot-time script using LOLO?  1533  6 Started by  Anonymous Note: Refer to the LogicLoader User's Manual, chapter 6, 'Boot-time Scripts' for more information about the following subject. Question: How can escape the executing of this script using LOLO, it seems if I put this contents in eeprom, there is no way I can go to LOLO prompt. Answer: There are two ways to get to the LoLo prompt. The first solution is to hold the 'q' key down and bring the kit up in BoLo. The serial_eeprom script you wrote for LoLo to jump to your application can be overwritt...

4 Replies and 1473 Views LCD problem  1473  4 Started by  tozyagcilar I am using the Logic Loader's losh prompt. I type the command 'funtest' and choose the DISP_LQ035Q7DB02 (which is the LCD I have). Only half of the square seems to be drawn properly. The botton half of the screen has horizantal strobing lines. The jumper settings on the LCD are as follows: - SPR is at - HORZ is at - VERT is at - I think this is a hardware issue, but maybe not. Did anybody come across this If this is a defect, what is the fastest way of replacing the part. Filling o...

1 Replies and 1429 Views Where is timer tick value located in LOLO?  1429  1 Started by  david.clarke I am using the 79520 SDK without an operating system and have a need for a timer tick. I notice that LOLO seems to use Time0 for a 1MS timer tick interrupt, which is exactly what I need. So rather than setting up my own timer-tick interrupt, I thought I would just read the tick value already kept by LOLO. Can someone tell me where the timer tick value that LOLO keeps is stored, and what size it is
