hello , i have a question about touch screen FT5302 . As in all touch screens when i touch a point on FT5302 it produce an interrupt that i use it to create an I2C transfer for giving coordination it give back o me. (because my controller is master and touch is slave) . in its data...
FT5046EE8( for touch screen)
Hello . I have a touch panel that its Ic is FT540EE8 . when i connects its wire to my board and touch it , it can send me via i2c some information . it has an interrupt signal and by touching the pad this signal go to low for a moment when i read received...
Hi . I work with DSP_C55 . I set IER1 in assembly to 0x0104 as below:
MOV #0104h,mmap(IER1)
then i define a function named Rgst as below:
MOV mmap(IER1),T1
MOV T1,*(_Myvar)
RET
in C program , in whlie part I call Rgst and compare IER1 register whit 0x0104 and result is true.
But when I set IER1...
hi . the image is very vague . if one stand in front of sensor ,it can be determined that it is an image of a person but not clear that who is he or she.
i do not know the error because of having an image but unfortunately a vague image . if i had no image i could analyze error but having a...
Hi, I want to display images on a LCD by using a ov6620 sensor. for this I use a FPGA that receives data from ov6620 and send them to LCD . I can manipulate OV6620’s registers and think all recommended points in its data sheet are considered but the image is not correct . in fact i have a dismal...
Hi , I thought by commenting a pin in UCF file (by # sign) in program(VHDL)it is considered as 'Z' , and has no role in the chip , in a project for driving a camera for getting view in LCD , i allocated 8 pins for each color R,G,B . in first try i used all pins in code but commented R and G...
hi
i want to send characters to printer model srp350ii . my microcontroller is pic16f876A that have paraller connection with my printer .i have read some datasheets of srp350ii and non of them say any thing about my problem . all them say commands for communication with srp350ii .i have not yet...
I want to receive and send a digit number(1,2,...,0,*,#) by mt8888 .it has an interface with DSPIC "33f.." . By initializing the mt8888 and applying some instruction I could send a digit and watched its related signal by osiloscope but I could not receive any digit . in fact I found that my...
