Legacy microcontrollers Forum Discussions
Hi,
I have CYTMA568 Touch controller. I have technical reference manual under NDA. Document No is 001-87666.
The TRM document in page 79, says "See CYTMA568 Touchscreen Controller Tuning Best Practices (Cypress specification 001-87715) for details on noise metrics." Can I get that document?
Show LessHi Sir ,
In the datasheet of CY95630H series , the sampling discribes as attched . I just want to konw ,when ' 1' or '0'comes ,
How many samples can be considered valid level ?
Thanks .
Show LessHi
I'm dealing with FM4 MB9BF56xR Family and I'm using Keil free license as IDE Tool.
The keil free licence allow to compile up 32KB of code.
What is in your opinion tyhe best IDE for designing with FM4 microcontroler?
Do you think exist some tool based on Eclipse as for other microcontroler family (for example STM32 micro)?

Show LessHello
I'm working with FM4 MB9BF56xR microcontroller and I have problem working wit DUAL Timer and PDL 2.1.
I Have already see a discussion regarding this topic and I' have correct the properr filer DT.c as reported in the topics.
But if I use the channel DT0 and DT1 in polling mode both are OK.
If I introiduce the callback function the softeare stop to run
If there is a right place I can attach my firmware
Thanks

Show Lesshi,we have a client who use the CY95F778(MB95F778),there are about 30 pieces of CY95F778 can't burning program by softune IDE or FLASH USB programmer.i check the PCB there is no problem,and the power supply is correct too,i try to use the softune IDE with MB2146-07-E to download the code,when i start to debug,an error appears "*** F9411S : Cannot continue debugging due to a CR trimming value error".
it seems that the CR trimming value may be invalid,i encountered similar problem before,sometimes the softune can adjust the CR trimming by itself,but this time the CR trimming can't be adjusted, the softune just appears error "Cannot continue debugging due to a CR trimming value error"and we can't download the code.and when i use the FLASH USB programmer,it also appears error"ERROR TRIM_CR 00,FF,",you can see the pic in attachment
the client want to know why does this problem happen,and how to solve this problem? How to adjust the CR trimming?
Show LessWe need to use the pin P2.9 as address line 22 for external flash memory, at the moment we’re using default setting for JTAG so we’ve this configuration:
Startup configuration (“User’s Manual capitolo 12.3.2):
Startup Mode - Internal Start From Flash
Debug Interface – from Flash
STSTAT.HWCFG Value – 0x07
P10[6:0] = X X X X 1 1 1
JTAG configuration:
P2.9 TCK
P5.4 TMS
P7.0 TDO
P5.2 TDI
We need to preserve every JTAG functionality (Programming, degub, … etc), so we want to swap the P2.9 (used as TCK) with the P8.5, and obtain:
JTAG configuration:
P8.5 TCK
P5.4 TMS
P7.0 TDO
P5.2 TDI
(User’s Manual CAP 12-3) We noticed that there’s a register called DBGPRR that define the JTAG pin configuration.
The questioni is: How we can change in a definitive way this register with the configuration that we need? We tried to find a way from memtool but nothing, same by setup it from firmware.
Thanks everyone. Show Less
Hello,
I am developing based on S6J337x.
As per safety requirement, how to make sure that port configuration and clock configuration will not change over time.
How we can solve it ?
Thanks.

Show LessHigh, I'm using IDE: IAR ARM 8.10.1, Controller: Cypress S6E2CCaj0a with PDL library.
When I used the _RAM.icf, everything works fine, now I switch to _ROM.icf memory configuration and I get a few problems with this.

Hi,
Good day.
We are a IC programmer manufacturer.
Recently our customer is asking the both MCU(MB90F462APFM and MB90F823BPMC1) for programming.
I didn't find the programming spec on the web side.
Could you help to provide the serial mode and parallel mode programming spec?
I have to support the both MPNs on our programmer. Thank you.
